Description

(5) SCRAPER CONVEYOR

The invention relates to the technology of transport, in particular to conveyors with elements that perform reciprocating movement, and can be used in the engineering industry for transporting metal chips from machine tools. A known conveyor for waste is directly for metal shavings, which has transport rods moving back and forth along a chute, with spatula-shaped grippers attached to the rod by means of pivots located across the corresponding rod rotatably attached to the rod. When the transporting rod moves along the chute in the working direction, the grippers are moved apart under the influence of shavings and, resting on the stops located on the rod, transport the chips. During the reverse movement of the rod, the grippers, under the action of the chip, move away from the stops and fold inwards-1. The disadvantages of this conveyor are the high intensity and low efficiency of the conveyor, since the rods with the grips are constantly under the pile of chips, which causes greater resistance to their movement. In addition, part of the chip during the reverse movement of the rod is carried to its original position. The hinges of the grippers operate in an environment containing fine metal chips, dust and dirt, which is the reason for their seizure. This leads either to idle strokes when the grippers are not moved apart, or to move the chips back and forth when the grippers do not fold. Therefore, the main task is to create more reliable scraper conveyor schemes that would provide only one-way movement of chips.

The closest technical solution to the proposed invention 0 is a scraper conveyor, including sliders, supported from a naprail cycide 8 chute, rods installed / slidable in sliders with the possibility of longitudinal displacement, scrapers, control levers and a reversing drive 2.

A disadvantage of the known construction is the unreliability of the installation of the elements of the step conveyor

to working stroke

Idle move. A reliable relocation of tolators (scrapers) from one to another position depends on the ratio of the rod's friction against the half-body and the slider relative to the guides. In case of equality of these forces or in case 5 when the first force is greater than the second, the movement of the rod is relative to the slider, and therefore the change in the position of the pusher gangs (scraper). may not occur. In this case, it will be necessary to increase the locking force of the slider relative to the guides, and accordingly the driving force

An important factor affecting the reliability of setting the pushers (scrapers) to the X position is also the ratio of the moment raising the pusher (scraper) f to the moment of lifting resistance, for example, from hooked chips, from contamination of the hinges.

In this construction, as the angle of inclination of the pusher towards the horizontal decreases, the lifting moment decreases with and the failure of the pusher in the retracted position becomes unstable.

The purpose of the invention is to increase the reliability of the conveyor.

This goal is achieved by the -ITO scraper conveyor, including sliders, support and guides, chute, rods installed 8 sliders with the possibility of longitudinal movement, scraper, control levers and reversing drive, each scraper made e double-arm, medium part of the upper end hinged to the slider and hinged to the actuating lever and the rod, wherein the hinge connecting the control lever to the scraper; located

on the side with respect to the hinge connecting the control lever with the rod 8 to the idling direction of the slide, 3 the drive is made in the form of a closed thrust element, CBR3J3HHO with the rod by means of blocks and its ends are attached to the slide.

The scraper conveyor consists of a metal gutter. Finally, the chip-assembly bin 2 ends, and includes several crawlers — Jv 3 with scrapers, a reversing drive H, a rope 5 and from the converting blocks 6, the whole system is mounted below zero

the shop floor mark of foundation 7 and is covered with metal flooring 8, consisting of separate sections, some of which are made in the form of opening hatches, in places of chip flow from

machine tools. In the structural assembly bu -1kere 2 there is installed a container 9 for a stand. {

The slider 3 is a rectangular frame 10 made of

the shelter located by the shelves

at each of the four rollers 11, the contact is supported on the guide shelves 12f mounted at the top of the side walls of the groove 1. Inside the frame 10 there is a staple 13, a front frame, the width of which corresponds to the internal width of the frame 10 of the slide 3, and shorter than her length. The rod 13 is supported by four rollers And on the shelves of the wound 10 of the slide 3 and bears on itself the deviation of the 1sh, their block 15, through which the ends of the rope 5 are fixed to the frame 10 of the slider | - a 3.

On the brackets 16 of the frame 10 of the slide 3, with the help of the hinges 17, two scrapers are mounted in the form of double-arm levers 18, one end of which with protrusions serves to grab chips and the other

by means of hinges 19 is connected to a control lever 20, which by means of hinges 21 and brackets 22 is connected to a rod 13 Sharnmr 19 is located relative to the hinge 21 in the direction of idling of the slide 3 (in Fig. 4), - Dimensions lever 8 and 20 and arrangement of hinges 17, 19 and 21 each other relative to IT'S ACCEPTED such that when the lever 18 is vertical, the control lever 20 is in a horizontal position, and in the retracted position of the lever 18 is in a vertical position. The reversing drive 4 is made in the form of a winch with a friction pulley which leads an endless rope 5, guided along the metal trough by means of deflecting block 6. In the working branch of the rope 5 several successively connected sliders with scrapers 3 are connected. depending on the length of transport and conveyor feed pitch. On the guide shelves 12 at the point of transition of the slide With scrapers 3 from working to idling, the plastic welded plates, which create temporary resistance to movement of the slide with scrapers 3 The scraper south-sheyer works as follows. When the reversing drive 1 is turned on translational (working; the cable 5 moves through the deflecting unit 15 to start right (fig .; rod 13 in the direction of the chip-collecting hopper 2. At the same time, the rod 13 moves from the i-wound 10 of the slide 3 to the right (FIG 1.5 and 6). Up to the stop in its right end wall, it further moves the slider 3 with scrapers. The boom 13 moving from the right by means of the control lever 20 and the hinges 17, 1.9 and 21 turn the scraper - double shoulders lever 18, vertical (working) position, while it transports the existing the groove 1 chips to the chip collector bunker 2. At a return (idle) course, the reversing actuator 4 is switched to reverse. In this case, the rod 13, the double-arm lever 18 and the control mag 20 take up the reverse movement, as is shown in sequence in FIG. , 5 and 6, thus the scrapers are completely removed from contact with the chips located in the groove 1. At the same time, the rollers 11 slide onto the plates, which create resistance to the movement of the slide 3 and facilitate the rearrangement of the rod 13 from the right to the left position (Fig. 5 and 6). The proposed conveyor allows shavings to be transported along a smooth chute, which reduces the resistance to its advancement, reduces the loads in, - (design elements 2-5 times and makes them more stable.
